sheet not saved; computer crashed; data lost

My brand new macbook pro retina completely seized up while I had DevonThink Pro open. My main database was open and everything there seems to have saved. But within that database I had two sheets that were open as separate windows. These do not appear to have saved. What I got when I opened up the database after I rebooted the computer was those two sheets as they had been several hours earlier. The data in there was seriously difficult to assemble so if there’s any way to get it back, I would really like to. Any help? Thanks.

Short of TimeMachine or similar backup util running, I don’t have anything particularly helpful to say. Sorry.
